It’s easy to do a cast list for Invaders because at least half the characters actually ARE a cast—in that amateur-but-very-publicized play Frank and Katia have to join. The others are people like parents who bring them to the theater; directors who put on the play; and audience members who come for the action-packed premiere in the final chapters. Only Katia’s aunt and uncle have no tie to the play and even they do mention it when reconnecting with her family (warning, do not reconnect with relatives who live near the city leader and have never wanted to talk to you before!)
And there will be more updates.
I live surrounded by cultivated fields that rapidly give way to wild flowers, wild plants, and wild life. I get most of my ideas while drifting innocuously around my house and some of those ideas get into print.
